"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects." (Robert A. Heinlein)

New toy on the desk: Raspberry PI 3

Just before Christmas I've been to a “traditional” electronics and surplus fair, here in Genoa, and bought myself, among other things, a Raspberry PI 3 (version B) board. My goal is to replace, as home server, the Raspberry PI I bought two years ago in order to take advantage of the more computing power offered by the new board. Additionally the older board will be set free for more “experimental” experiments. As “accessories” to my new Raspberry board I bought a (clear) plastic case, a 16GB micro SD card and en external 2.5'' USB hard disk.

Installation and first tests

I first downloaded latest Raspbian release, the “Lite” version since I'm going to use it as a headless server. Like I did last time I copied the disk image on the 16GB SD card using the “dd” command.
sudo dd if=2016-11-25-raspbian-jessie-lite.img of=/dev/sdd
All worked fine but I had to fix a couple of things. The image I copied at the first tentative didn't boot, I had to remove all memory card partitions using Gparted then repeat the copy process. The disk copied after the second tentative works fine, I don't know if problem was because a failure in the first copy or because of how the card was pre-formatted.
The latest Raspbian release has SSH demon disabled by default to enable it I had just to add an empty “ssh” named file on the memory card root folder.
touch /media/maxx/boot/ssh

Test drive: (Raspberry PI) Pixel on the EEEPC 900

I own a Raspberry PI since two years but I used it as headless server from the very beginning. I have, almost, never seen its window manager apart from some remote desktop experiment. I so learned only recently how latest Raspbian released are shipped with a new lightweight desktop environment: Pixel. More recently I also learned that Pixel has been released for X86 “common” computers I decided to test how it runs on my EEEPC 900 netbook.

First impressions

I downloaded Pixel ISO disk image from here and prepared a bootable USB disk. Raspberry page suggested using Etcher to prepare the boot disk but UNetbootin did the job as well as usual.
The boot process went smooth and quite fast, and Pixel here is my very first screen-shot of Pixel.
